“…Castro et al [41] evaluated the corrosion behaviour of electrospun PHBV coated magnesium alloy for biodegradable implant applications, proving that the electrospun coated sample showed better corrosion resistance than the bare metal. In addition, electrospinning technique also allows the fabrication of porous coatings that resemble the extracellular matrix of the body, promoting cell growth for tissue healing or used as drug releasers for infection control [42]. Nafi et al [43] studied the corrosion behaviour of pure magnesium and magnesium alloy (AZ91) coated with PLLA electrospun fibres.…”

The use of surface engineering techniques to tune-up the composition of nanostructured thin-films for developing functional coatings with advanced properties is a hot topic within the scientific community. The control of the coating structure at the nanoscale level allows improving the intrinsic properties of the surface compared to bulk materials. A nanodeposition technique with increasing popularity in the field of nanotechnology is electrospinning. This technique permits the fabrication of long and continuous fibres on the micro-nano scale. The good control over fibre morphology combined with its simplicity, cost-effectiveness, easy exploitability and scalability make electrospinning a very interesting tool for technological applications. This review is focused on the use of the electrospinning technique to protect metallic surfaces against corrosion. Polymeric precursors, from natural or biodegradable to synthetic polymers and copolymers can be electrospun with an adequate control of the operational deposition parameters (applied voltage, flow rate, distance tip to collector) and the intrinsic properties of the polymeric precursor (concentration, viscosity, solvent). The electrospun fibres can be used as an efficient alternative to encapsulate corrosion inhibitors of different nature (inorganic or organic) as well as self-healing agents which can be released to reduce the corrosion rate in the metallic surfaces.

“…Tera et al [36] proposed strategies of two-stage forming consisting of finishing and roughening as the most appropriate avenues based upon analytic hierarchy order. Palumbo et al [37] accomplished enhanced formability of biocompatible AZ31B magnesium alloy sheet at high rotational speed of the forming tool with delayed cytotoxic influence.…”

Traditional manufacturing operations require a long time and capital for prototype development and small batch production. Forming processes necessitate component specific and expensive dies since their preparation and design are time-consuming. In latest years, incremental sheet metal forming has acquired good attraction owing to its ability for small-batch productions and prototyping with generic tooling and short lead time. In this paper, a review of literature works has been presented describing investigations carried out on the formability of lightweight alloys, mainly Al alloys, Ti alloys and Mg alloys, during single point incremental forming (SPIF) process, considering the deformation mechanism, formability assessment techniques, forming limit curves, effects of influencing factors, and the effect of heating.

“…PCL, a biocompatible polymer with a low degradation rate and biodegradability, has been extensively investigated for biomedical applications. Additionally, it is processable through a variety of technologies due to its solubility in a vast variety of organic solvents, glass transition temperature, and low melting point [46]. Additionally, due to its ease of processing, nontoxicity, and high strain failure rate, PCL attracts great attention.…”

The development of biodegradable implants is certainly intriguing, and magnesium and its alloys are considered significant among the various biodegradable materials. Nevertheless, the fast degradation, the generation of a significant amount of hydrogen gas, and the escalation in the pH value of the body solution are significant barriers to their use as an implant material. The appropriate approach is able to solve this issue, resulting in a decrease the rate of Mg degradation, which can be accomplished by alloying, surface adjustment, and mechanical treatment. Surface modification is a practical option because it not only improves corrosion resistance but also prepares a treated surface to improve bone regeneration and cell attachment. Metal coatings, ceramic coatings, and permanent polymers were shown to minimize degradation rates, but inflammation and foreign body responses were also suggested. In contrast to permanent materials, the bioabsorbable polymers normally show the desired biocompatibility. In order to improve the performance of drugs, they are generally encapsulated in biodegradable polymers. This study summarized the most recent advancements in manufacturing polymeric coatings on Mg alloys. The related corrosion resistance enhancement strategies and future potentials are discussed. Ultimately, the major challenges and difficulties are presented with aim of the development of polymer-coated Mg-based implant materials.
